The package not only came smashed (like it had been dropped a time or two), the manifold did not fit my 1998 6.5L turbo diesal (chevy k2500). It had to be cut and welded in spota because waiting any longer for another manifold was not an option.

The old turbo exhaust manifold in my 1998 6.5 diesel was completely rotted. I searched for a replacement and for a while only found used manifolds. When I found this manifold I was a little skeptical but when it arrived I was impressed that all the bolt holes seamed to be right on for the turbo and the side the bolts to the head of the engine. I did have to mill out one of the exhaust ports with a die grinder because it looked like the casting went bad and the welded to fill it. There was too much weld which substantially blocked the exhaust flow. However after 15 minutes of grinding it was completely passable and has not given me an issue.
